I just think it is a shame that you can't get Bairstow, Foakes and Buttler in the team at the same time. In theory, they would be great, but in reality is doesn't work.
Buttler isn't strong enough as a batsman on his own but is probably the most naturally talented sportsman in the squad, Bairstow should be England's 3 or 5 but has killed his technique despite being England's best test batsman in 2016ish.
Foakes is the better gloveman but he had a bad year with the bat in County Cricket.
I'm a huge fan of Foakes and I want him to play for England again. I just wish Bairstow and Buttler were good enough to play as batsmen, because if those two stepped up the plate as they can (and should, really), England would be a far stronger batting side. Bairstow's loss as a batsman in particular is a real loss for the test side, but his technique just isn't working!
Does the rule 'even a faulty clock is right twice a day' strike true with Buttler, perhaps? I'm not sure.
The class of that 2016 South Africa tour held so much promise. Bairstow, Ballance, Taylor...
